用法說明
How is "It's" different from similar structures?What usage mistakes are common with "It's"?
it's + 形容詞 + to do vs. it's + 形容詞 + doing
- it's + 形容詞 + to do 通常用於描述一個普遍的事實或一般情況，強調做某事的性質或特點。
- it's + 形容詞 + doing 則更常描述特定、具體的經驗或情境，強調正在進行或親身經歷的過程。
- 某些形容詞（如
nice,great,fun）與doing連用時，會帶有「享受過程」的含義。 - 在正式寫作或表達建議、必要性時（如
important,necessary,essential），幾乎總是使用 it's + 形容詞 + to do 的結構。

常見錯誤
What are common mistakes with "It's"?Which "It's" sentences look correct but are wrong?
×The cat licked it's paw.
✓The cat licked its paw.
「it's」是「it is」或「it has」的縮寫，表示「它是」或「它已經」。而「its」是所有格，表示「它的」。這裡指的是貓的爪子，是所有格，所以要用「its」。
×Its a beautiful day today.
✓It's a beautiful day today.
這裡的意思是「今天天氣很好」，是「It is」的縮寫，所以必須用「it's」。使用所有格「its」在這裡是錯誤的。
×Its your book?
✓Is it your book?
在疑問句中，不能直接使用「it's」來提問。必須將動詞「is」移到主詞「it」前面，形成「Is it...?」的結構。
×It's many people in the park.
✓There are many people in the park.
當表示「某處有某物/某人」的存在時，應該使用「There is/are」的句型，而不是「It is」。這裡的主詞是「many people」，所以用「There are」。
×It's my friends who are coming.
✓My friends are the ones who are coming.
雖然「It's... who/that...」是強調句型，但當被強調的主詞是複數時（如 my friends），後面的動詞仍應與主詞一致（are）。然而，在口語中，用「It's」開頭強調複數主詞有時會被接受，但在正式寫作中，最好重組句子以避免這種不一致。這裡提供一個更自然的改寫方式。
×The report states it's imperative to act now. (在非常正式的學術或法律文件中)
✓The report states that it is imperative to act now.
在非常正式的書面語（如學術論文、法律文件、官方報告）中，通常應避免使用縮寫形式（如 it's, don't）。應完整寫出「it is」。
